The quote form takes a ZIP code; for West Columbia that is 29169 (Census 2020 ZCTA to county subdivision and ZCTA to place relationship files, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt and https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_place20_natl.txt, checked 2026-10-19).
Of the 8,516 occupied homes in West Columbia, 33% heat with natural gas, 0% with heating oil, 65% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4575850, checked 2026-10-19).
Electricity already heats 65% of West Columbia homes, ahead of gas at 33%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
West Columbia has about the Lexington County oil share of 0% and 4 points less electric heat than the county's 69% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US45063, checked 2026-10-19).
West Columbia has 9,318 housing units, 3% built before 1940 and 55% before 1980, with 25% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4575850, checked 2026-10-19).
West Columbia has 13 points fewer homes built after 2000 than the county's 38% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US45063, checked 2026-10-19).
The median West Columbia home was built in 1976 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4575850, checked 2026-10-19) and the median home has 5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4575850, checked 2026-10-19).
61% of West Columbia homes are single-family detached, 13% are in two- to four-unit buildings and 18% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4575850, checked 2026-10-19).
45% of West Columbia homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4575850, checked 2026-10-19), so beside the 61% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
West Columbia has 9 points fewer detached houses than Lexington County overall (70%) and 11 points more five-plus-unit buildings than the county's 7% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US45063, checked 2026-10-19).
45% of West Columbia homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4575850, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
No electric utility is on file for West Columbia on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in West Columbia is $56,912 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4575850, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
Heating design temperature: 24F.

That 24F figure is the Lexington County cold-day number a West Columbia heat pump is sized against, so ask the installer to show the system's heating output at 24F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median West Columbia home has 5 rooms and was built around 1976, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
